What are the new BTL application process changes implemented by Paragon Bank for HMOs and MUBs?
Quick Answer
Paragon Bank recently updated its application process for HMOs and Multi-Unit Blocks (MUBs), requiring a full valuation report prior to offering and streamlining legal processes for experienced landlords.
## What are Paragon Bank's current application process changes for HMOs and MUBs?
Paragon Bank, as of August 2026, has implemented specific changes to its application process for Houses in Multiple Occupation (HMOs) and Multi-Unit Blocks (MUBs), primarily focusing on valuation and legal requirements. These adjustments are designed to streamline the process for landlords dealing with these complex property types, reflecting a more tailored approach to specialist buy-to-let lending. For instance, a notable change is the shift to a single valuation for an entire MUB, rather than individual unit valuations, potentially reducing costs and processing time for investors.
Historically, the valuation process for MUBs could be cumbersome, often requiring multiple individual valuations even if the units were under one title. Paragon's updated stance simplifies this, allowing a block valuation, provided certain criteria are met. This aligns with a broader industry trend where specialist lenders are adapting their offerings to better suit the nuances of complex investment properties. Furthermore, the bank has refined its legal requirements, particularly concerning the title structure of MUBs, offering more flexibility for properties with either a single freehold title or multiple leasehold titles within a block, as long as the underlying security is sound.
These changes are part of Paragon Bank's continuous effort to support professional landlords and are specific to their product range. While other lenders may have different policies, Paragon's adjustments aim to reduce the administrative burden and potential costs associated with mortgaging HMOs and MUBs. For example, a landlord purchasing a MUB of four units previously requiring four separate valuations costing £300-£500 each, could now pay a single block valuation fee, potentially saving £900-£1,500 on valuation costs alone.
## Does Paragon Bank offer different criteria for HMOs and MUBs?
Yes, Paragon Bank maintains distinct lending criteria for HMOs and MUBs, acknowledging their inherent differences in structure, management, and rental income generation. For HMOs, the focus remains heavily on the licensing requirements and the local council's specific regulations, such as minimum room sizes (e.g., 6.51m² for a single bedroom, 10.22m² for a double bedroom). The bank will assess the property's compliance with these regulations and the landlord's experience in managing such properties. The maximum number of occupants and households allowed will also be a key consideration in their assessment.
For MUBs, the primary distinction lies in the property's title structure and how income is assessed. MUBs are typically self-contained units, each with its own tenancy agreement, unlike HMOs which involve shared facilities. Paragon evaluates MUBs based on the collective rental income of all units and applies an Interest Cover Ratio (ICR) stress test, which might be around 140% rental coverage at a 5.5% notional pay rate, though this is lender-specific. The valuation approach, as mentioned, treats the block as a single entity, which can affect the loan-to-value (LTV) calculation and the overall borrowing capacity.
While both property types offer higher yields than standard buy-to-let, the bank's underwriting process for each is tailored to mitigate specific risks. For instance, an HMO with 6 occupants generating £3,000 per month will be assessed differently to a MUB of 3 self-contained flats each generating £1,000 per month. The legal and operational complexities are distinct, and Paragon's criteria reflect this granularity to ensure responsible lending to experienced landlords.
## What impact do these changes have on landlord costs and timescales?
The changes implemented by Paragon Bank are primarily designed to reduce both the financial costs and the timeframes associated with securing finance for HMOs and MUBs. The most significant direct impact on costs comes from the revised valuation policy for MUBs. By allowing a single block valuation instead of multiple individual unit valuations, landlords can see savings on surveyor fees. For a MUB with, for example, five units, previously requiring five individual valuations at an average of £450 each, the cost would be £2,250. Under the new policy, a single block valuation might cost £750, representing a saving of £1,500.
Regarding timescales, consolidating the valuation process into a single instruction and report can substantially shorten the mortgage application timeline. Fewer individual reports to commission, review, and approve means a faster progression through the underwriting stage. Additionally, simplified legal requirements, where applicable, can reduce the back-and-forth between solicitors and the lender, further accelerating the process. While specific time savings are difficult to quantify precisely as they depend on individual case complexity, reducing the number of critical external reports generally shaves weeks off the overall process, benefiting investors who often operate on tight acquisition deadlines.
These efficiencies free up landlords' capital and time, allowing them to focus on property acquisition and management rather than administrative hurdles. It also allows for clearer, more predictable cost projections when budgeting for a purchase. A landlord buying a £1 million MUB could now factor in a more efficient valuation cost structure and potentially shave 2-3 weeks off their completion timeline due to reduced administrative burden, compared to previous processes.
## Are there any specific property types or structures excluded from these changes?
Paragon Bank's updated processes are specifically designed for qualifying HMOs and MUBs and do not extend to all complex property types or structures. Properties that do not fit the strict definitions of an HMO (e.g., requiring mandatory licensing for 5+ occupants from 2+ households) or a MUB (e.g., multiple self-contained units under a single title or with specific leasehold arrangements) might still fall under different, potentially more complex, lending criteria. For example, a property with commercial elements or a genuinely mixed-use property (like a shop with a flat above, which is treated as commercial for SDLT purposes) would not benefit from these specific residential BTL process changes.
Certain unique or highly unusual property structures might also be excluded or require bespoke assessment. This could include properties where the legal title is overly complex, or where there are significant covenants or restrictions that could impact marketability or security for the lender. Additionally, properties where the landlord lacks sufficient experience in managing HMOs or MUBs, or where local authority licensing is problematic, might also face different underwriting scrutiny, even if the property itself fits the definition.
It is always essential for landlords to consult directly with Paragon Bank or an experienced mortgage broker specializing in complex buy-to-let to confirm eligibility for these streamlined processes. A property configured as a traditional holiday let, for instance, would typically be under different lending products and criteria than those explicitly for long-term ASTs in HMOs or MUBs, despite both being investment properties.

## Investor Rule of Thumb
Always understand the specific lending criteria for your property type and landlord experience level before committing to a purchase, particularly for specialist assets like HMOs and MUBs.
## What This Means For You
Paragon Bank's adjustments for HMOs and MUBs demonstrate a clear trend among specialist lenders to adapt to the needs of professional landlords, streamlining once-complex processes. These changes reflect an understanding that the right finance can significantly impact your portfolio's efficiency and profitability. Most landlords don't face undue delays because of a lender's process, they face them because they haven't aligned their deal with the right lender and their specific criteria.

Steven's Take
The shift from Paragon Bank to a single valuation for Multi-Unit Blocks is a practical change that experienced investors should welcome. I've seen countless deals get bogged down or become uneconomical due to multiple valuation fees, especially on larger MUBs where individual unit valuations add up quickly. This move not only saves direct costs, potentially thousands of pounds on a significant acquisition, but also cuts down the time spent waiting for multiple reports. Time is money in property, and any process that accelerates a deal towards completion is a win. However, it's critical to remember that these changes are specific to Paragon and will likely be for professional landlords with a good track record. Don't assume all lenders are following suit, and always ensure your property fully complies with all local regulations before applying. The due diligence still falls to you, the investor, to ensure the property fits the lender's exact criteria.
